#4 Kevin Owens vs Sami Zayn
Last year, we witnessed the best build up to a Wrestlemania match with Chris Jericho's and Kevin Owens' bromance being the focus of Raw for large parts of the second half of 2016. These two produced the best TV product of Raw, including the exceptional Festival of Friendship segment, that all but confirmed that betrayal storylines tend to work well for WWE fans during Wrestlemania season.
When Sami Zayn turned heel to help KO defeat Shane-o-Mac at Hell in a Cell, the speculations were that WWE might be going to the same path as "JeriKO" and have KO eventually turn on Sami Zayn, setting up a meeting with the Underdog from Underground in New Orleans. However, with plenty of babyface superstars (Randy Orton, Bobby Roode and even Shane McMahon) waiting for big Wrestlemania matches, it seems highly unlikely that WWE would turn either of the two face during this Wrestlemania season.
Destined to do this Forever? Maybe. But this year these two might have to fight other superstars.
